notes from mission control
parachute deploys at mach 2.0
inflate parachute 2 seconds earlier
turn to entry attitude maneuver- point heat shield forward
8/110ths of a degree pointing error (can have up to 10 degrees for safe entry)
reduced to .37 degrees pointing degrees.
vent freon coolant prior to entry. causes spacecraft to wobble. craft fires small control thrusters to prevent wobbling
HRS signature indicates hrs has turned off not vented
jetison of the cruise stage or cruise stage seperation
hematite
lander battery current zero: unexpected (due to telemetry drop out) batter current is now as expected
1.8 degrees pointing error
calibration tones indicating status of spacecraft
pressure 3 psi indicating that freon has vented correctly
peanuts eaten for good luck
.79 degrees pointing error
cruise stage has been jetisoned properly
seperation springs 45 centimeters a second

non flash memory mode
master sequence first since anomoly
moving toward guarded condition
batteries are fully charged. thermal looks good (a little cold but just because of early shut down)
flash hardware is in fact ok. file management module in the software is not robust enough for the operations they were engaged in when the problem occurred
error on motor control board (another hypothesis.
solar event wednesday
flash energy sensitive to high energy protons and neutrons
on the way to normal recovery
